To all whom t may concern:

Be it knownthat i, LoUIs SCHWARTZBERG, a citizen of the United States, residing at Chicago, in the county of Cook and tatate -of lllinois, have invented a new and useful improvement in a Cushion for Egg Cases, of which the following is a specification.

My invention relates to packing andstoring receptacle boxes, and the like, and more lo particularly to a cushioning device to be placed in the bottom, top lor other convenient place in the container in order to permit of a cushioning of the articles packed therein. Another object of my. present invention is the provision in a cushioning de- 4vice of astructure that will permit of the circulation of air below the same and for the purpose of Ventilating the receptacle and permitting circulation of fair about the i2@ articles contained in the receptacle.

This present device is capable of employnient in connection with boxes of candy, egg cases, and, in fact, any type of container or receptacle adapted to receive and store articles in a cellular structure'. n egg cases, as is well known, as well as in types of candy boxes and boxes for ornaments, it is the practice to employ aplurality ofparallel longitudinal and transverse walls that' intersect to form cells or spaces into which the articles are deposited and are separated from each other. Usually the articles upon the bottom and top tiers of the receptacle or lbox are subject to little or no @E cushioning, and in the case of egg crates the weight of the eggs above thev bottom tier frequently causes the eg s in said tier to receive dama ing impact W en in transit so that they ecome broken. Also in the packing d@ of eggs forl cold storage there is little or n'o ventilation in the top and bottom rows ofthe crate and the eggs become musty due to moisture and poor circulation of' air. With my present inventiomi am able to overcome l5 the defective ventilation and circulation of air, and am also able to provide a dependable cushion that prevents articles in the top or bottom tiers becoming broken through impact lor jar.

ll prefer to accomplish the divers objects of my invention in substantially the manner hereinafter described, and as more particularly pointed out in the claims.

Figure 7 is a fragmentary corner view of the bottom of a modified structure, with thev flat removed.

For the purpose of convenience, l have lillustrated and described my invention as applied to egg cases or crates, but it will be understood that theprinciples are adapted for use inconnection with any type of cellular or similar receptacles or storage vessels.

Referring more particularly to Figure 1, it willl be observed my improved cushion preferably comprises a rectangular plate 10 fomed of al sheet of strawboard, cork, wood, or any other suitable material, that is substantially fiat upon its upper surface, as seen in Figures 3 to 6, inclusive, is provided with a .plurality of large recesses or apertures l1, and intermediate these large recesses or Openings are smaller apertures. 12

that extend entirely through the structure.

rlhe recesses or apertures 11 are arranged, as seen in the drawings, in six` rows with six -in each row for an egg case, and are sllghtly smaller in diameter than the diameter of an egg, and the edges of recesses or apertures 11 upon the upper face of the structure are countersunk, asat 13, (Fig. 2) so as to avoid presenting a sharp corner to the article contained in the receptacle. course, the countersinking o r beveling of the edge may be dispensed with. When apertures are formed, the material between the if. desired, of. i

Seme 'provide feet la upon the bottom etv the plate, and the space surrounding the small apertures 12 is cut away, about two- ,thirds the thickness of the material, to prosageways for air to circulate throughout. the under portion of the cushion and the corners of the cushion are provided with substantially square feet or projections 18.

When the cushion has been placed with the feet down in a section of an egg crate, the ordinary flat 19, which is usually of three-ply fibre board, is placed upon the top of element or plate 10, after which the cellular sections `20 are superimposed .thereon with a dividing flat 19 between each cell section. The bottom layer or tier of eggs in the case rests upon the lowermost flat 19 and are positioned above the respective recesses or large apertures 11 in the cushion struc- 'ture so that the bottom tier of eggs will be v afforded a slight cushion and prevented from breaking.

The structure heretofore described may be modified by making the ,recesses or large openings angular instead of circular, in which event the appearance of the bottom of the structure will be as seen in Figure 7, in which the recesses or openings 11'a are Octagonal andv the feet 14a are rectangular in outline, while the cutout portions 16a in the edges are likewise rectangular instead of segmental in shape. In the modified structure just described the intermediate smaller apertures 12a are made round, as in the prerlhe structure in Figure 7 may be found to be more desirable in some instances for the reason that the air passageways 15a or channels'between the feet and below the top are somewhat wider and of greater area than in thev preferred form,

rshown in Figure 1. rlhe manner of usingl the structure shown in Figure 7 is the same as that described in the preferred form. and it will be understood that further modifications are possible without departing from the principles li have disclosed.

1. A cushion for cellular packing receptacles comprising a substantially flat plate,

ine/reas and elongated feet extended longitudinally and transversely upon the bottom of said plate.

2. A cushionl for cellular packing recep tacles comprising a substantially flat plate having a plurality of recesses therein, and feet positioned longitudinally and transversely upon the bottom of said plate between the recesses.

3. A cushion for cellular packingy receptacles comprising a substantially stiff plate supported upon and spaced a slight distance from the bottom of the receptacle, said plate provided with a plurality of recesses, and a yielding Hat coactingwith one face ofy said plate whereby said flat may be depressed at thel locations of said recesses.

4:. lin an egg-crate, a plurality of cell-sections, flats interposed between said sections, and a cushion structure consisting of a substantially rigid element having a plurality of supporting feet; said element having recesses between said feet and registering with the cells in said sections, and a flat positioned between said element and the adjacent cell section.

5. ln an egg-crate a plurality of cell-sections, flats interposed between said sections, and a cushion structure consisting of a substantially rigid element, a plurality of longitudinally and transversely disposed feet extending downwardly from the bottom of said element to support the latter above the bottom of the crate, said element provided with a plurality of apertures disposed between the longitudinal sides of said feet, and a flat positioned between said element and the adjacent cell-section.

6. A cushion for cellular packing receptacles comprisin a suitable plate, and a plurality of longitudinally and transversely arranged projections upon the bottom of said plate; said projections being spaced from
